ok…First you need to download WIPSoft.dwl(you will find this inside the WIP folder, under the software suite installations)  
file on the modem, then issue AT+WOPEN=1, further you will have to configure and activate the gprs using AT+wipcfg and AT+wipbr  
commands. You should go through WIP command guide properly to know the commands to be used.
